Four Reasons Why McDonald's Mighty Wings Flopped

Instead, CEO Don Thompson said that the chicken wings aren't the smash success it had hoped for.

While Mighty Wings apparently met internal targets, the item was "was not strong enough to offset" weak sales trends, Thompson said on a conference call today.

Here are some of the reasons they flopped.

1. Price: In McDonald's terms, Mighty Wings are a premium product. The wings come in packs of three for $3.69, five for $5.59, and 10 for $9.69. Thompson said the prices, which are similar to Buffalo Wild Wings, were "not the most competitive."

2. Spice: Thompson said the wings were too spicy for many customers' tastes.
